This shouldn't break anything, no variable name is changed.
Documentation and strings are fixed, strings that do not come in a 'command' or those that are required for 'pwncat' to work are not changed.
For linux, we used to send one or two EOFs via C-d to the process to
signal exit, however this was inconsistent. Depending on the previous
input from the attacker, sometimes one was needed, sometimes two.
Sometimes, we even observed more than two being needed. Instead, we now
simply loop sending one at a time and checking for the end delimeter.
This will be slightly slower, but avoids hangups or accidentally closing
the shell.
